UNITED STATES PATENT OFFICE.

CHARLES S. WATSON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO ALLEN MIDDLETON, OF SAME PLACE.

ICE-PICK.

SPECIFICATION forming part of Letters Patent No. 225,670, dated March 16, 1880.

Application filed February 6, 1880.

To all whom tt may concern Be it known that I, CHARLES S. WATSON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented an Improved Icelick, of which the following is a specification.

The object of m yinven tion is to make a cheap and simple ice-pick by which blocks of ice may be readily and edectively severed without that waste of ice which results from the manipulation of the ordinary pick.

In the accompanying drawings, Figure 1 is a side View of my improved ice-pick, and Fig. 2 a perspective view.

The implement consists of three main parts, namely: the bar A and its chippingblade a, 'the spring B, and the heavy handle D, attached to the spring B near the outer end of the same.

The bar A is thick enough to be rigid, or

comparatively rigid, and its blade a is formed by turning down a portion of the bar, the lat ter being preferably of steel, and beveling the turned-down portion so as to reduce it to a sharp point, the cutting-edge being rounded transversely, as shown in Fig. 2.

The spring B is secured, by riveting or otherwise, to the outer end of the bar A, and the normal condition of the spring is that shown in Fig. 1.

0 The handle D is made of cast-iron, and is secured to the spring in any convenient manner, a projection, 6, being preferably formed on the under side of the spring, so that when the spring is depressed the said projection will 3 5 strike the bar at the point or, immediately above the chipping-blade.

In manipulating the implement the operator grasps the handle D in the manner shown in Fig. 2, adjusts the edge of the chipping-tool to the desired point on the block of ice, and then strikes the bar at a; with the projection c as many sharp blows as may be necessary to split off the ice at the point desired, the cutting-edge of the blade remaining in contact with the ice and at the point to which it was 5 first adjusted during the above operation, so that there must necessarily be less waste of the ice than in splitting it with an ordinary ice-pick, which, however well aimed the pick may be, rarely strikes theice twice at the same point.

It is not essential that the handle should be heavy. It may, for instance, be made of wood; but a heavy handle of cast-iron is always to be preferred, for the reason that the momentum acquired during its movement renders the implcmentmore convenient to handle and more effective in its operation.

I claim as my invention 1. The within-described ice-pick, the same consisting of the bar A, having a chipping blade, and the spring B, secured to the said bar and provided with a handle, D, all substantially as set forth.

2. The combination of the bar A and its chipping-blade, the spring B, its metal handle D, and projection 6 below the handle, all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHAS. S. WATSON.
